welcome to hcm.
red rashes over fece may be due to various reasons.
eyebrow involvement probably due to seborrhic dermatitis
dryness,itching increases it.
so moisturiser helps.
dermadew caloe will also help.
if there is itching you can take antihistaminic tablets.
other moisturisers also helps.
as its decreasing there is no need to worry.
it may reccur but you can repeat the treatment.
if become severe consult a dermatologist
